non FINGER.

' Application filed March 24, 1924. Serial No. 701,506.

To all whom it may concern Be it known that I, DEWEY LEE J ONES, acitizen of the United States, residing at Columbus, in the county ofMuscogee and State of Georgia, have invented new and useful Improvementsin Rod Fingers, of which the following is a specification.

This invention relates to protector mechanism for looms, the generalobject of the invention being to provide means for preventing injury tothe protector rod which carries the binder engaging finger when thedagger engages the frog on the failure of a shuttle to be boxed.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side elevation of a portion of a loom showing my invention in use.

Figure 2 is an enlarged view of the improved finger.

In these views, A indicates the loom frame, the lay being shown at 1,the shuttle box at 2, the shipper at 3, the knock off lever at 4 and thefrog at 5. The spring actuated dagger rod is shown at 6 and the daggerat 7 for engaging the shoulder 8 on the frog when the lay movesforwardly and the shuttle has failed to be .boxed. The protector rod isshown at 9 and is connected with the dagger rod and the binder fingershown at 10 and is clamped on the rod 9- by the set screws 11.

My invention comprises in providing the finger with a spring pressedplunger 12 which passes through a hole 13 formed in the upper end of thefinger and has its head 14 engaging the binder 16. The spring is shownat 17 and has its ends bearing against the finger and the head, and 14indicates a lock nut on the outer end of the plunger.

As is well known, when a shuttle fails to be boxed the spring on thedagger rod will force the dagger downwardly so that it will engage theshoulder 8 on the frog 8 to cause the same to engage the lever 4t andthus stop the loom through well known mechanism. When a loom is properlyboxed the binder 16 engaging the finger 10 will prevent the spring onthe dagger rod from lowering the dagger into engagement with theshoulder on the frog and thus the loom continues to operate until ashuttle fails to be boxed and the parts come into operation as beforedescribed and stop the loom. The sudden check given the lay and itsattached parts by the engagement of the dagger with the shoulderfrequently causes the arm or rod 9 to bend or break but with the springplunger on the finger this damage to the rod cannot take place as theplunger will be pressed outwardly, thus permitting a certain amount ofmovement of the rod 9 and the finger 10 to prevent damage to the rod. Assoon as pressure is relieved the plunger is returned to its normalposition by its spring.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is A binder finger for use upon looms having an enlargedtransversely bored lower portion, a protector rod removably securedwithin the bore and having its opposite end portion connected with theloom mechanism, a plunger member transversely disposed within the upperend of the finger, a compression spring encircling the plunger andarranged between the plunger head and finger, a lock-nut arranged uponthe opposite end of the plunger, and a binder arranged adjacent to andresiliently engaging the head of the plunger whereby the loom willcontinue to operate until a shuttle fails to be boxed.

In testimony whereof I affix my signature.

DEWEY LEE JONES.
